I0s7 update not available on my iPhone 4S?

My iphone doesn't even have the option to get the new i0s7 update… It just says my iphone is up to date. I just now today downloaded the i0s6 update so I don't know if that has anything to do with it or not? It seems everyone else has already gotten the i0s7 update but mine isn't even giving me the option to update it

Wait a day or two before downloading iOS 7.

Everyone will be downloading it on the 18th and Apple's servers might be too busy.

Backup your phone before upgrading. You need the newest version of iTunes if you use iTunes to install iOS 7.

You have to connect your phone to the computer, then go to iTunes and you should see where it says summary afterwards you should see update and you click update

Mines updated today. I have the 4s & my iPad mini received the update also.
